It also includes consultancy on deep-water tunnel designs, the dam and hydroelectric power station, the tender for material supply, supervision of construction work, site installation, on-site testing and commissioning.

“The project will contribute to the development of Hatta, and meet its developmental, social, economic, and environmental needs. It will also contribute to the achievement of the Dubai Clean Energy Strategy 2050,” said Saeed Mohammed Al Tayer, managing director and CEO of DEWA.

The hydroelectric power station will make use of the existing water stored in the Hatta Dam, which can store up to 1,716 million gallons, and an upper reservoir that will be built in the mountain to store up to 880 million gallons.

During off-peak hours, turbines that use clean and cheap solar energy will pump water from the dam to the upper reservoir. During peak-load hours, when production cost is high, turbines operated by the speed of waterfall from the upper reservoir will generate electricity that will be connected to DEWA’s grid.
